` f `4 clarin.` (o1. :ss-12a) This invention relates to an full or toysize. i, l,

The object ofthe invention is the provision. of means holding. one legthat may be vplaced in two different positions corresponding to threedifferent heights of the boardproper abovethe `floor ory othersupporting surface. These. I means also function as alock locking the`legs of the` board in folded or collapsed position upon thelbottom sideof the board proper so that theA entire struc--y ture may be handled orstored away in a narrow space without the legs spreading andhamperingthe user. l

The invention consists in the details of .construction whereby certainimportanty advantages are attained and which will be described. I g

The novel features of my invention will hereinafter be particularlyclaimed.

The description is illustrated by the accompanying drawings in which:

Figure 1 is a .bottom plan view of the ironing board with the legs inposition collapsed against the bottom of the board;

Figure 2 is a longitudinal central line 2-2 of Figure 1;

Figure 3 is a lcentral longitudinal section through the board with the`legs extendedthe ironing board of section on lowermost ends of whicharegomitted and the latch set in a position giving the board the` maxi-Figure 4 is a section similar to that of Figure 3 with the distinctionhowever that the latch holds f the legs in a position in which theheight of the board above the floor is less than that of the precedingfigure;

Figure 5 is a detail sectional view of the pivot means attached to thebottom of the board and to which one pair of the legs are pivoted;

Figure 6 is a transverse section on line 6-6 of Figure 4;

Figure 7 is a longitudinal detail section on line 'l-l of Figure 6through the latch set in the position of Figure 4.

Similar reference characters are employed to designate similar partsthroughout the figures.

The board proper B of moderate thickness is generally Oblong and has itslongitudinal edges approaching one another towards the right hand end.Beneath the board and near the left hand right-angled end of the sameare blocks 2 secured to the board by nails 3 or other fastening means.These blocks have aligned apertures 4 through which extends a rod 5having ends protruding beyond the blocks and passing through apertures 6in the upper portions of downwardly V diverging legs 1 which are iorconnected at an intermediate point by a rod 8 and near their bottomvends by a rod 9. .f I To the bottom of the board a latch IU is pivotedby a screw nail or other fastening means The latch is provided with anotch I2 extending parallel to the plane of the board and formed in theend remote from pivot II. Another notch I3 is formed in the bottomsurface of the latch, between the pivot I I and notch I2.

Upon rod 8 is pivoted another shorter pair of legs I4 the upperconverging ends of which carry a rod I5 while the lower diverging endscarry the rod I6. Owing to the fact that the leg structure I4 is shorterthan leg structure 'I and passes through the latter, the former may befolded into the latter in which position the latch I0 may be turned tothe position of Figure 1 in which the rod 8 is lodged inthe notch I2 andthe entire board is locked together. If it is desired to use the board,the latch IIl is turned to the position of Figure 4, the board isinverted, the legs are unfolded to a crossed positionin which the rod 1I5 can be lodged in notch I3. If the user finds the board inconvenientlylow, he may adjust the same to a higher elevation by lifting the boardso as to disengage rod I5 from the notch I3, then turning the latch to areverse position of Figure 3 in which he may rest such rod in the samenotch now located on theopposite side of the pivot or in the end notchI2, if a still greater height of the board above the :door surface isdesired.

Having described the invention what I claim and try to secure by LettersPatent is:

1. In combination with an ironing board provided with a stand on theunderside thereof composed of crossed hinged legs foldable into oneanother and one of which legs is pivotally connected at its upper end tothe underside of the board. a block rotatably connected to the undersideof the board and provided with a notch in one end thereof and a secondnotch in its underside and between said end and the point of connectionof the block to the board, said rst notch being engageable with thehinge of the legs for locking the stand in a collapsed position againstthe board when the block is disposed with said first notch facing towardthe pivot of said leg to the board, a rod extending transversely fromthe upper end Of the other leg, and said first notch being engageable,in the same position of the block with the rod for holding the stand inone extended position, said second notch being engageable with the rodin said aforementioned position and in a second position of the blockintermediate of their ends to, an intermediatev portion ofv the'rstpairof legs and in crossedrelationship, a rung connectingcorresponding,v
